System working process
Vehicle entrance process
  At the entrance of parking lot, there is a toll collector who hold a wireless handheld intelligent terminal issues IC card to drive When the car comes in. (the toll collector will do some related operation on the card so that  the card will storage the corresponding data, such as the time of entrance, the license plate NO etc. important information). Then the driver takes the card away and keep it. This IC parking card will be as the only evidence for charging and releasing when he leaves. 
  After issuing card, the signal of telecontrol will be sent out automatically. The system of telecontrol will control the barrier gate to lift, then the car entrys to management area. Meanwhile, wireless handheld intelligent terminal will record the useful information.
      The flow chart is as below:


The process of exit
  When leaving the parking lot, the driver needs to show IC card to toll collector. The collector will  use handheld terminal read the information in the  card and calculate the fees, show the receipt to driver, and then after driver's confirmation, the collector charges the fees and release the car out. 。
  After taking back and swiping the card, the signal of telecontrol will be sent out automatically, the barrier gate lift, then the car leaves the management area. Meanwhile, the PDA will record the useful information.
